Pidgin crashing when doing finds too much

Hello all
I use pidgin 2.2.0 which is an older build because this is the last
version that doesn't appear to have this problem. Every version I have
tried after crashes. To reproduce this all you have to do is:
Connect into a chat room (I use yahoo chat)
Let a lot of text accumulate (probably let it sit 3 hours in a busy room)
control-f
Enter some text that will occur often
Run the find many many times
I've never had a problem not having this happen to me. I use the chat
rooms enough and find enough that it happens. Good luck at finding the fix.
